and EcoBKV60XF, Lanxess has introduced three PA6 compounds containing 30, 35 and 60%-by- weight respectively of recycled fibre made from glass waste as calculated using the ISCC Plus-certi- fied mass balance method. This product family has been extended to include even more compounds based on PA6 and PA66. Lanxess is also using the recycled glass fibres for the mechanical reinforce- ment of its Pocan PBT compounds. Early products include Pocan EcoB3235 and the flame-retardant EcoB4239, each of which contain 30% by weight of recycled glass fibres, as calculated using the certified mass balance method. Eurotec has developed Tecomid Eco, technical

the high technical requirements required in this sector. In addition, a further three injection grades have been added to the Repsol Reciclex range of non-food packaging, incorporating between 50-80% recycled plastic content. These three new grades are especially suitable for household cleaning and drugstore product containers with chemical resistance requirements and paint containers with good mechanical resistance to enable stacking, among other properties. Lanxess has introduced Durethan BlueBKV60H2.0EF, with 92% of the raw materials used in this easy-flowing compound replaced with sustainable alternatives. The company says that the new grade is the first product from the Scopeblue series. The brand label identifies products that either consist of at least 50% circular (recycled or bio- based) raw materials, or whose carbon footprint is at least 50% lower than that of conventional products. One of the raw materials used in the production
of this PA6-based high-performance compound is cyclohexane from sustainable sources – meaning cyclohexane that is either bio-based, recycled bio-based or produced by means of chemical recycling. The material is also strengthened with 60%-by-weight of glass fibres comprising industrial glass waste instead of mineral raw materials. The alternative raw materials that Lanxess uses in the precursors for PA6 are chemically identical to their equivalents of fossil origin (drop-in solutions), so Durethan BlueBKV60H2.0EF exhibits the same characteristics as the virgin material and can be processed just as easily using exactly the same production tools and facilities with no conversion work needed. Lanxess adds that the compound can be used for the production of car front ends, brake pedals and oil pans, for example. The company is currently working towards 100% sustainable raw materials in this compound. With Durethan EcoBKV30H2.0, EcoBKV35H2.0

recycled PA compounds produced from industrial textile fibre waste, with partially or 100% recycled PA polymer content. Eurotec says that its PA recycling formulation, testing and processing, provides reliable and traceable material solutions using characterisation, viscosity, mechanical and thermal tests. Tecomid Eco displays similar test performance to that of virgin materials. Its main characteristics are high thermal stability, good stiffness and tensile strength, as well as good chemical resistance and reduced environmental impact. The company says that Tecomid Eco grades are suitable for a range of industries such as automotive, electrical and electronics, sports and leisure, industrial and home appliances. Tecomid Eco NB and Tecomid Eco NA are available in various grades with up to 60% glass or carbon fibre content, and flame retardant grades are also available. For example, Tecomid Eco NA43 GR30 BK005 HS exhibits good thermal, chemical and long-term mechanical properties and it is safely used for pedal housing, cooling fan housing, air intake manifold, oil pans and engine cover automotive applications. Tecomid Eco NA43 GR25 NL (BK002) XA43, which is a PA66, 25% glass fibre reinforced, heat stabilised and flame retardant compound, graded V-0 at 1.6mm, exhibits good mechanical properties. It is used in switches and oven lights for household applications. Finally, due to high mechani- cal and UV stability performance, Tecomid Eco NB40 GR30 BK009 provides solutions to metal replacement in guardrails for a safe working environment. The company has also developed Tecotek Eco,
Tecopet Eco and Tecodur Eco, which are technical recycled PC, blends of PBT and recycled PET, and recycled PET compounds respectively. The 10% glass fibre reinforced material with halogenated flame retardant properties, Tecotek Eco PC44 GR10 GR003 ZG70, is used in electricity meter housings. It is graded V-0 at 1.6 mm according to UL94, with good dimensional stability. Tecopet Eco PT74
